K24 Bottom end rebuild need opinions

[amant02]

get 4 piston racing to build you a motor, get it shipped over, get Adrian at sas to tune it


and enjoy your 300+ naturally aspirated horseies on 98

hehe

oh and do yourself a massive favor- don't listen to amant, he is the village idiot.

Stock comp on a 'built' NA motor?
Stock rods as well?



A cheaper alternative would be to just find another k24, stick your current k20a head on and retune
Or find another k24 and get a 163 with appropriate cams/ valvetrain and tune on e85, amazing how much the americans are makeing with seemingly simple setups.

Talk to the pros and read up on k20a.org

I have a feeling you haven't attempted to build.

Please dont call me the village idiot, when your post make no sense.

The cost of making 300+ kfrank?

The weakness isn't in the rods, its the rod bolt that will hit its limit 1st on the k24. There a heaps more things that will go wrong before your stock rod shits itself.

And your cheaper alternative, is the more expensive way. DO NOT BUY ANOTHER K24 & JUST SLAP IT ON. It will slap you in the face when you bounce of the limiter.

Reason for stock comp k24a3 - Boost. Same as E85 explanation.

Reason for stock CU2 Piston - Do you even know its compression? TSX would be even better. CU2 will be more readily available in aus.

Also E85 is not worth it unless you have gone all out NA and still requiring more. Cost for performance gained is minimal. Boost is where you really see the benefit. You can run more boost before hitting the detonation threshold.

He already has 2 engines. Just rebuild to basic specs to best you can afford. Speak to an engine builder. He will clear the questions you have, can be done for under 5k if things go your way. Maybe remove/install and disassemble motor yourself. Get a shop to do all machining balancing and assembling.

I would be buying majority of the parts from overseas to save on cost. Aussie Vendors sometimes want too much.

Stock rods, TSX pistons, Supertech valves k20 head. $$$ add up quickly and then a decent cam

Stock k24 and turbo is cheaper lol

Thank you.

uwotm8? thats 10.5:1 with a stock head.

if you're adding bost why does it matter which block you use, OP's got a k20 head.

uwotm8?

Whats this unicorn fart TSX piston you're talking about? Cu2 pistons?

CU2? thats 11:1 before you slap a K20 head on or resurface the head, that's good for boost how?


why in the world would you take a motor already with comp > 10:1, then ADD compression, and then add boost?

Also E85 is not worth it unless you have gone all out NA and still requiring more. Cost for performance gained is minimal. Boost is where you really see the benefit. You can run more boost before hitting the detonation threshold.

uwotm8?

if you got Boost and got new injectors why wouldnt you look at E85?

[u mad?]

LOL thanks for proving my point amant

Wut? okay. This makes no sense.

Das not for boost no shit.

This has been my point for stock comp

Another reason why E85 would be the last thing you do to a NA Motor

Are you still burt hurt from me telling you that a $2000 reflash was a rip off?

[Super-DA9]

I have a feeling you haven't attempted to build.

No offense, but to be fair you haven't built any engines either as far as we've seen lol

[Fredoops]

Are you still burt hurt from me telling you that a $2000 reflash was a rip off?

Where's this 2000 dollar reflash? You mean flashpro?

Wut? okay. This makes no sense.

Op's already got a k20a head. Did you not read?

[amant02]

I know, but I has attempted. Gave up on high comp K series build when I was given quotes on parts and prices.

Are okay mate? You said dosnt matter which block he chooses.

Why wouldn't this matter. Dsnt matter na or boost. The 2.4L block matters.

I think your being the potato.

[RenzokukenJ]

OP's got a k20 head.

Amant got prawn head

[amant02]

It was cheaper for me to buy my rexie than to do a fully sick k24 NA build on my dc5r

[amant02]

Also if you guys wanna argue high comp isnt for boost. Contradicting myself. OP wont have the funds of a manufacture to RND.

have you seen any of the new engines coming out.

Nearly all are high comp turbo from factory. Twin scroll ofcourse.

Thinking about doing something and immediately giving up doesn't really meet the definition of 'attempting' as I understand it lol

Way i see it. Lucky I didn't go thru wit it. Would've been very disappoint after. Waste of cash. Turbo is the way to go.
